Upgrading the management server on zCX
Prerequisites
Docker (version 18 or later) or Podman (version 4.4.1 or later)
Task 1: To obtain the installation files and license key
Go toElectronic Product Distribution (EPD) and log in.
- Using the search bar, search for either BMC AMI Cloud Data or BMC AMI Cloud Vault. Both product files are composed with the same binaries.
- Click the version that you want to download.
- On the Product tab, select the files and click Download.
- Select the License Information tab and download the temporary license key.
To obtain a full license key, go toSupport Central and select Case Management.
Open a license key request by clicking on Create New Case and filling in the required information.
Task 2: To upload the s390x installation zip file
Upload the s390x installation zip to the zCX instance using scp or any other tool in binary mode.
Copy the s390x installation zip from the zCX instance to the alpine container:
Task 3: To stop BMC AMI Cloud
Stop the server and remove the BMC AMI Cloud containers that are running by using the following commands, replacing v.r.m with the current fix pack version:
docker rm model9-v<v.r.m>
Task 4: To prepare the installation artifacts
In the Alpine container, open the BMC AMI Cloud artifact:
docker volume create model9db_initdb
# Stopping the old alpine container
docker stop dummy
docker rm dummy
# Running an alpine container and mounting the model9 docker volume
docker run -d --rm --name dummy \
-v model9:/root \
-v model9db_initdb:/docker-entrypoint-initdb.d \
s390x/alpine tail -f /dev/null
docker exec -it dummy sh
cd /root
unzip /root/model9-v2.8.2_build_ebcddfb-server-s390x.zip 'model9*'
# Verify the existence of the diag directory. Create it if needed.
mkdir diag
# Backup the /conf directory.
tar -czf conf-backup.tar.gz conf
# Exit from the alpine container.
exit
Copy the docker container images from the alpine docker container (the one that was used during the initial installation):
Task 5: To load the new release artifacts
Load the new release docker containers:
Task 6: To back up the server before the upgrade
Run each command separately and check the results:
docker cp dummy:/root/conf-backup.tar.gz ./conf-$fileStamp.tar.gz
docker exec -it model9db pg_dump -p 5432 -U postgres -d model9 -f /tmp/model9db-$fileStamp.dump
docker cp model9db:/tmp/model9db-$fileStamp.dump ./model9db-$fileStamp.dump
docker exec -ti model9db rm /tmp/model9db-$fileStamp.dump
Task 7: To update the PostgreSQL shared memory setting
Run the following command:
docker stop model9db
# Remove the Postgres container
docker rm model9db
# Start Postgres docker container on zCX issue:
docker run --shm-size=256m -p 127.0.0.1:5432:5432 \
-v model9db:/var/lib/postgresql/data:z \
-v model9db_initdb:/docker-entrypoint-initdb.d:z \
--name model9db --restart unless-stopped \
--network model9network \
-e POSTGRES_PASSWORD=model9 -e POSTGRES_DB=model9 -d s390x/postgres:14.5
Task 8: To start the BMC AMI Cloud server
Run the new release container using the following command:
--sysctl net.ipv4.tcp_keepalive_time=600 \
--sysctl net.ipv4.tcp_keepalive_intvl=30 \
--sysctl net.ipv4.tcp_keepalive_probes=10 \
-v model9:/model9:z -h $(hostname) --restart unless-stopped \
-e "TZ=America/New_York" \
-e "CATALINA_OPTS=-Xmx2048m" \
--network model9network \
--name model9-v2.8.2 model9:v2.8.2.ebcddfb
